Lewis Hamilton's "spectacular" leadership and maturity in the wake of the Monaco debacle has thoroughly impressed Mercedes' head of motorsport Toto Wolff.

Sunday brought with it an excruciating end to a memorable week for the Formula One world champion, having followed up his lucrative new deal with the Silver Arrows by gaining his first ever pole in the principality.

It was a position Hamilton looked set to turn into a dominant, lights-to-flag victory, only for a remarkable miscalculation by his team to cost him.

The decision to pit under the safety car handed team-mate and rival Nico Rosberg a gift-wrapped win, followed home by Ferrari's Sebastian Vettel and a clearly distraught Hamilton.

Unlike recent years, though, the British driver kept his counsel after the race and, with the few things he did say, remained positive - a development which impressed Wolff.

"Compare the Lewis from a year ago in a difficult Monaco race to the Lewis we have seen now," the Mercedes chief said.

"He has come out of losing a race which he owned, which he controlled with a maturity and as a leader in a spectacular way which makes me very happy, to see him coming out strong.

"I think we have all grown into a team. We have brought the team to where we are today all together, despite the ups and downs and difficult moments, and he's very much part of that team and part of the decision making of the team.

"He motivates and inspires so many people within the team in the same way he is inspired by lots of the clever boys out there. He's just an integral part."

Wolff is not expecting any pent-up frustration to boil over next time out in Canada.

"No, when you see the way he has matured or grown I see no risk whatsoever," he said.
